About the NPOST exam
Overview of the National Police Officer Selection Test (NPOST)
The National Police Officer Selection Test (NPOST), developed by Stanard & Associates, Inc., is one of the most widely administered entry-level law enforcement screening tools in the United States. State highway patrols, county sheriff offices, and municipal police departments across more than thirty states rely on the NPOST to identify qualified recruit candidates before they advance to physical agility testing, psychological evaluations, and background investigations.
The examination measures fundamental cognitive capacities that correlate directly with on-the-job success at law enforcement training academies and in field operations. Rather than testing prior legal knowledge or police tactical procedures, the NPOST evaluates a candidate's practical literacy, basic mathematical competence, attention to detail, and ability to construct clear, accurate incident reports under timed conditions.
Comprehensive Syllabus and Exam Sections
The NPOST assesses four foundational cognitive modules:
1. Mathematics
This section tests practical arithmetic without the aid of a calculator. Candidates must solve fundamental math problems that simulate real-world police duties, such as calculating distance, speed, vehicle braking marks, fuel efficiency, shift payroll hours, and restitution amounts. Concepts tested include:
- Addition, subtraction, multiplication, and long division with whole numbers and decimals
- Percentage calculations and fractional conversions
- Basic algebraic formulas and practical word problems
2. Reading Comprehension
Officers must interpret statutes, departmental general orders, court warrants, and investigative summaries. This module measures the candidate's capacity to read passages related to police procedures and extract accurate details. Skills evaluated include:
- Locating specific facts within dense procedural text
- Making reasonable inferences without drawing on outside knowledge
- Identifying the main idea and underlying purpose of written directives
3. Grammar, Mechanics, and Vocabulary
Clear communication in law enforcement prevents miscarriages of justice and administrative confusion. Candidates are presented with incomplete sentences and must identify the grammatically correct word or phrase to complete them. Tested elements include:
- Subject-verb agreement, pronoun references, and modifier placement
- Punctuation, capitalization, and standard American spelling
- Choosing precise vocabulary in formal reporting contexts
4. Incident Report Writing
Law enforcement professionals spend a significant portion of their shifts documenting investigations. This section evaluates a candidate's ability to transform raw witness observations, suspect descriptions, and incident notes into a coherent, chronologically ordered narrative. Candidates must answer questions based on completed police face sheets and incident reports, demonstrating competence in factual sequencing, clarity, and structural completeness.
Essential Test Day Rules and Regulations
- Valid Identification: Candidates must present government-issued photo identification (such as a valid driver's license, passport, or military ID) during test check-in.
- No Calculators Permitted: Scratch paper is provided for the mathematics portion, but mechanical, electronic, or digital calculating devices are strictly prohibited.
- Strict Time Limits per Module: The NPOST is strictly partitioned into individually timed sections. Test takers may not read ahead to future sections or turn back to previous sections once time is called.
- Personal Items and Electronic Devices: Mobile phones, smartwatches, recording equipment, backpacks, and personal study guides are banned from the testing room. Possession of any electronic device can result in immediate disqualification.
- Pencil and Paper Integrity: Candidates taking the paper-pencil format must mark responses clearly using standard #2 pencils. Stray marks or incomplete erasures on bubble sheets may negatively impact optical scanning.
- Silence and Testing Decorum: Talking, signaling other examinees, or attempting to view another candidate's examination paper leads to immediate expulsion and forfeiture of police candidacy.
Scoring System and Passing Benchmarks
The NPOST utilizes a percentage-based scoring model across its four sections. While individual law enforcement agencies set their own specific hiring cutoffs, the standard benchmark established by Stanard & Associates requires candidates to achieve a minimum score of 70% in each individual section (Mathematics, Reading Comprehension, Grammar, and Incident Report Writing).
Many highly competitive police departments require an overall composite score of 80% or higher to advance to the oral interview board. Scoring below 70% in any single section results in an overall failure of the exam, requiring candidates to wait for a mandatory cool-off period (typically 30 to 90 days, depending on departmental policy) before retesting.
Strategies and Preparation Tips for NPOST Success
- Eliminate Calculator Dependency Early: Practice manual arithmetic, long division, and percentage operations by hand weeks before your scheduled examination date to build speed and accuracy.
- Read for Literal Evidence: On reading comprehension items, resist using personal bias or assumed police protocols. Base every answer strictly and exclusively on the explicit text provided in the prompt.
- Drill Report-Writing Mechanics: Focus on standard sentence structure, eliminating run-on sentences, and avoiding dangling modifiers when reviewing grammar concepts.
- Pace Yourself Against the Clock: Because each subtest is timed separately, practice answering questions within strict 1-to-2-minute intervals to avoid leaving unanswered questions before time is called.
- Analyze Practice Test Errors: Take full-length diagnostic mock examinations to pinpoint whether your weaknesses stem from calculation errors, vocabulary traps, or time management deficits.
Test rules
- Must present a current, unexpired government-issued photo ID upon arrival at the test site.
- No calculators, smartwatches, mobile phones, or unauthorized electronics are allowed inside the examination room.
- Test takers must adhere strictly to the individual section time limits and cannot navigate across sections outside designated instructions.
- Examinees must use approved #2 pencils on paper-based test answer forms.
- Communication with any other examinee during test administration leads to immediate disqualification and removal.
- Scratch paper provided for mathematical calculations must be surrendered to proctors prior to leaving the testing room.
Score grading
Scored on a 100% scale per section. Candidates generally must achieve at least 70% in each of the four individual sections (Mathematics, Reading Comprehension, Grammar, and Incident Report Writing) to pass, though some hiring agencies establish higher competitive cutoffs.

FAQs
NPOST stands for the National Police Officer Selection Test, an entry-level written exam developed by Stanard & Associates and used by law enforcement agencies across the United States.
Most law enforcement agencies require a minimum score of 70% on each of the four individual sections, though competitive departments often look for composite scores of 80% or above.
No. The use of calculators is strictly prohibited during the NPOST. All mathematical calculations must be completed by hand on scratch paper provided at the test center.
The NPOST covers four specific subjects: Mathematics, Reading Comprehension, Grammar/Mechanics, and Incident Report Writing.
Retake policies vary by department and testing jurisdiction, but most agencies enforce a mandatory waiting period of 30 to 90 days before an applicant can re-register for the exam.
